For years people have been saying that mankind is disrupting the “natural order” of things, causing the global climate to reach record temperatures never before reached. But after looking at the actual facts, I’ve begun to question that popular view of global warming.
First, the whole thing about “record temperatures” is misleading. We’ve only had useful thermometers since about the 17th century, and most of our actual records of temperature go back only 150 years or so. And these records are for the most part very localized, mainly being in the region of western Europe and eastern North America. Records for the Southern Hemisphere have been limited. It’s only been in recent years that we’ve really started taking global measurements, and those show that while in some of the Northern Hemisphere temperatures are rising, in many areas temperatures are actually dropping. Nor is there really any agreement or absolute certainty on what the readings we get regarding temperature and greenhouse gases and whatnot mean.
And even if we accept the extrapolations showing that the entire planet’s climate is heating up, that’s not really a new thing. If you look at ice core records and other sources, you’ll see that the global temperature over the past few hundred thousand years has had an impressive series of highs and lows, many of the highs being greater than they are now. And even further back in time, temperatures were much higher than anywhere on those graphs (it appears that for much of its history, the Earth hasn’t even had ice caps at all). Global temperatures have been rising and falling since well before mankind.
So it seems to me that the planet’s just going about its normal climate fluctuations. The natural state of the planet is change, not one steady temperature. So really, what the people who are trying to get us to stop the climate from changing are wanting us to do is to keep things unnaturally steady, so that the climate is more comfortable for us. If we let the temperatures get higher the way they would normally do, then we’ll have to sweat more, and we’ll lose some of our waterfront property to rising sea levels, and we’d have to change a lot of things like our agricultural methods. Personally, I have nothing against trying to keep the planet nice for the members of humankind (I’m one myself, after all), but I find it rather hypocritical of all these people claiming that we need to stop artificially affecting the climate, when what they’re actually suggesting we do seems to be just that.
